Extinct New Zealand eagle may have eaten humans
Sophisticated computer scans of fossils have helped solve a mystery over the nature of a giant, ancient raptor known as the Haast’s eagle which became extinct about 500 years ago, researchers said Friday.
The researchers say they have determined that the eagle – which lived in the mountains of New Zealand and weighed about 40 pounds (18 kilograms) – was a predator and not a mere scavenger as many thought.
Much larger than modern eagles, Haast’s eagle would have swooped to prey on flightless birds – and possibly even the rare unlucky human.
Using computed axial tomography, or CAT, the researchers scanned several skulls, a pelvis and a beak in an effort to reconstruct the size of the bird’s brain, eyes, ears and spinal cord.
They compared their data on the Haast’s eagle to characteristics of modern predator birds and scavenger birds to determine that the bird was a fearsome predator that ate the flightless moa birds and even humans.
Scientists believe the Haast’s eagle became extinct about 500 years ago, most likely due to habitat destruction and the extinction of its prey species at the hands of early Polynesian settlers. Before the humans colonized New Zealand about 750 years ago, the largest inhabitants were birds like the Haast’s eagle and the moa.
Scofield said the findings are similar to what he found in Maori folk tales. “The science supports Maori mythology of the legendary pouakai or hokioi, a huge bird that could swoop down on people in the mountains and was capable of killing a small child,” he said.
New Zealand paleontologist Trevor Worthy said the study did a good job of proving the eagle was a killer.
